Practice Questions for Respiratory System Questions
Question 1 of 5
The chloride shift occurs in order to
Correct Answer: B
Rationale: The correct answer is B because the chloride shift occurs to transport bicarbonate ions into the blood plasma. This process helps maintain acid-base balance in the body by exchanging chloride ions for bicarbonate ions to regulate pH levels. Choice A is incorrect as the chloride shift is not related to forcing oxygen into tissues. Choice C is incorrect as the chloride shift does not produce salt for the cytosol of blood cells. Choice D is incorrect as the chloride shift does not directly produce carbonic acid but rather helps in maintaining the balance of carbon dioxide and bicarbonate ions.
Question 2 of 5
Which of the following anatomical structures is not part of the conducting zone?
Correct Answer: C
Rationale: The correct answer is C: alveoli. The conducting zone of the respiratory system includes structures that transport air to and from the gas exchange sites. Alveoli are the primary sites of gas exchange, not part of the conducting zone. Pharynx (A), nasal cavity (B), and bronchi (D) are all part of the conducting zone as they help in air transportation but do not directly participate in gas exchange like alveoli do. Therefore, alveoli is the correct answer as it does not belong to the conducting zone.
Question 3 of 5
The filtering and keeping the mucus and dirt away from our lung's performed by
Correct Answer: A
Rationale: The correct answer is A: cilia. Cilia are tiny hair-like structures in the respiratory tract that sweep mucus and dirt out of the lungs to keep them clean. Bronchioles are small airways in the lungs through which air passes, not involved in filtering. Hair in the lungs is not a natural structure; it would be harmful. Choice D is incorrect because not all options listed are involved in filtering and keeping the mucus and dirt away from the lungs.
Question 4 of 5
smoking is one of the cause of
Correct Answer: C
Rationale: The correct answer is C: emphysema. Smoking is a leading cause of emphysema due to the damage it causes to the air sacs in the lungs. This damage leads to decreased lung function, shortness of breath, and other respiratory problems. Hypoxia (choice A) is a condition of low oxygen levels in tissues, not directly caused by smoking. Cancer (choice B) is also linked to smoking, but emphysema is specifically associated with lung damage. Macrosis (choice D) is not a recognized medical condition related to smoking or any other factor.
Question 5 of 5
The 75-year-old patient presents to the emergency department with shortness of breath, fatigue, and a dry cough. When information leads the nurse to suspect that this patient should undergo workup for histoplasmosis?
Correct Answer: B
Rationale: The correct answer is B because living on a farm and raising chickens increases the risk of exposure to histoplasmosis, a fungal infection commonly found in soil contaminated with bird droppings. Raising chickens can lead to exposure to bird feces, which may contain the histoplasma fungus. The other choices (A, C, D) do not directly involve exposure to environments where the fungus is commonly found, making them less likely to lead to histoplasmosis workup.
